2 Claims. (01. 62-1085) A further object of the invention is to-provide a freezing tray of this character embodying a plurality of spaced apart tubular members in which the ice is frozen together with means for detachably mounting th tubular members in liquid tight engagement with a bottom plate whereby to facilitate the removal of the ice from the tray.

A further object of the invention is to provide a device of this character of simple and practical construction, which is efilcient and reliabl in use, relatively inexpensive to manufacture and otherwise well adapted for th purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a top plan view, Figure 2 is a side elevational view,

Figur 3 is an end elevational view,

Figure 4 is an enlarged fragmentary sectional view taken substantially on a line 44 of Figure 1,

Figure 5 is an enlarged fragmentary sectional the lower ends of tubular members 1 extending downwardly in spaced apart relation from an upper clamping plate 8 having openings 9 therein in alignment with the tube to provide an open upper end therefor.

A gasket ill or rubber or other suitable material is placed in the recesses 8 in engagement with the lower end of the tube to provide a liquid tight seal at the lower ends of the tubes.

The clamping plates 5 and 8 as well as the tubes I 7 maybe constructed of any suitable material and where such parts are constructed of molded or fibrous material a metallic sleeve may be em"- bedded in the lower clamping plate 5 in which the lower end of a bolt I2 is threadedly engaged, the upper end of the bolt extending upwardly through the upper clamping plate 8 and secured thereto by means of a wing nut iii of substantially fiat construction and provided with a relatively thick central portion I4 countersunk in the top of the upper clamping plate 8, as shown to advantage in Figure 9 of the drawing. To the ends of the lower clamping plate 5 are pivotally attached the lower ends of clamping bolts I5 adapted for swinging outwardly at the ends of the view of the lower end of the centerclamping bolt,

Figure 6 is a fragmentary top plan view of a modified tray construction,

Figure '7 is a fragmentary side elevational view thereof,

Figure 8 is a fragmentary side elevational view showing the ice forming tube removed from the bottom clamping plate, and

Figure 9 is a fragmentary sectional view taken I substantially on a line ee of Figure 2.

I Referring now to the drawing in detail wherein for the purpose of illustration I have disclosed a preferredembodiment of the invention, the numeral 15 designates a bottom clamping plate of elongated construction and formed in its upper surface with a plurality of annular recesses 8.

The recesses 6 are adapted to loosely receive tray and providing slots I 6 at the ends of the upper clamping plate 8 for receiving the upper portions of the bolts in clamping engagement therewith by wing nuts I! threaded on the upper ends of the bolts ii.

The tubes 1 may be constructed of cylindrical formation as illustrated in Figures 1 to 4 inclusive, or the tubes may be of square shape in cross section as illustrated at l8 in Figure 6 of the drawing and adapted to have their lower ends inserted in complementary-shaped recesses in the clamping plate.

By clamping the upper clamping plate 8 and lower ends of the tubes 1 in recesses in the lower clamping plate a liquid-tight seal will be provided therefor whereby to prevent the escape of water lower when placed in the tubes.

After the water has become frozen the tubes 1 may be removed by releasing the bolts 12 and I5 and lifting the tubes and upper clamping plate 8 upwardly in the manner as illustrated in Figure 8 of the drawing.

In view 01" the foregoing description taken in conjunction with the accompanying drawing it is believed that a clear understanding of the construction, manner'of use and advantages of the device will be quite apparent to those skilled in the art. A more detailed description thereof is accordingly deemed unnecessary.

It is tobe understood however, that even though 3 I r l. have herein shown and described a preferred embodiment oi. my invention. that the same is susceptible to certain changes fully comprehended by the spirit oi the invention as herein described,

- and the scope of the appended claims.

Having thus described the invention, what I claim is:

1. A freezing tray for refrigerators comprisin having a plurality of openings, tubes formed on the under side of the upper plate beneath the 0. said lower plate having a plurality of recesses adapted to receive the lower ends or the fupper and lower elongated plates, said upper plate 4 tubes for closing said lower ends, and bolts securing the plates to each other.

' 2. A freezing tray for refrigerators comprising plates to each other.
